NIM / CAMAC FAN-TRAY UNITS

UEL 01 / CEL 01 (CE conform)

The static pressure reaches 8mm water column.
The air inlet can be selected either from front or bottom side,

• Mains on/off switch with LED
• Status-LED's (ok, overload, overtemp., fan fail)
• Open collector alarm output(LEMO) and buzzer alarm for overload and/or overtemp
• Test sockets with LED’s for all DC-voltages

Weight: 4kg
MTBF: >45 000h / 40°C

UEL 02 / CEL 02 (CE conform)

• Mains on/off switch and LED
• 2-pos. fan velocity switch with LED
• "Auto off" switch and LED (Fan fail circuit disabled)
• Status-LED's (ok, overload, overtemp., fan fail)
• 6-position selector switch to choose the DC-output which shall be displayed on the dual LED display (voltage and current separated)
• Buzzer alarms for bad status, overload, overtemp. and fan failure

The power supply trips off in case of any fan failure, if "auto off" is not disabled.

Weight: 5kg
MTBF: >45 000h / 40°C

UEL 03 / CEL 03 (CE conform)

The UEL 03 series is a micro processor based fan tray and control unit with multi-functional alpha numeric display. Three axial long life DC-fans (low accoustic noise!), which are mounted on on ball bearing. Each fan in induvidually controlled, the fan speed is variable from 1200 to 3000rpm.

Air inlet is either from bottom side (>540 m³/h full cooling efficiency) or from front side (400 m³/h). The maximum static pressure reaches <8mm water column.

• Mains on / off
• Display mode
• Fan speed
• Trip off Disable
• Network Programming

The alpha numerical display can show voltages, currents, temperatures, power consumption of inserted modules and fan speed as well as fail reasons. In programming-mode trip off-points may be adjusted, like current limits to any lower value than maximum. If these defined values are exceeded, the PS 336 trips off.
(All facilities according to CERN- CAMAC-Note 46-04)
Weight: 5kg,
MTBF: >65 000h / 40°C

Options: Prepared for or equipped with remote control interfaces: CAN-bus, HS-CAENET or GPIB

UEL 05 M

The UEL 05M is a turbine based high pressure fan tray unit for CAMAC crates reaching up to 270 m³/h air flow against 20mm water column static pressure by centrifugal fans.
The given air flow is not suitable to cool more than 1000W power dissipation

All operation instruments (switches, LED's, display) are similar to the UEL 02M series.
